INA2143U/2K5E4 Product Details

INA2143U/2K5E4 Overview


There is a SOIC case package that contains the instrumentation amplifiers. The instrumentation amplifier in this picture is of the OPERATIONAL AMPLIFIER-type. We are approaching the 14h termination of the year. In total, there are 14 pins on this op amp ic. This linear amplifier should be powered by an 5V battery. There are two types of Operational Amplifier op amps in this case, and this device falls into one of them. The input offset voltage is 500μV. On the buffer amps, there are 2 channels that can be used. For this linear amplifier to work, the temperature should not be below -55°C. In order to avoid damage to the product, operational amplifiers should only be used at temperatures below 125°C. Under 36V is the minimum supply voltage for this electric component. Over 4.5V is a recommended supply voltage for buffer ampsIn order for this electronic part to be conducted successfully, you should use a dual supply voltage of 18V. 950μA quiescent currents are flowing through buffer op amp.
